Find My Kid page

Overview

Our project aims to reconnect parents back to their missing children. If a child wanders off in a crowded place, in can be scary for both the parent and the child. Our project will allow parents to reunite with their kids quickly and efficiently. The child will carry an arduino + bluetooth module device, which will communicate through bluetooth to the parent’s cellphone. When the child and parent are separated by a pre-set distance, both the child’s device and the parent’s phone will respond. The child’s device, which will be carried in a small, portable, and kid-friendly box, will emit a loud noise. Meanwhile, the parent will get a notification on his or her cellphone.

Objectives

Our main goal for FindMyKid is to successfully establish communication between two devices: one being carried by the parent and one being carried by the child, using an arduino. Our project is successful if the receiver automatically starts to emit a beeping noise once it is outside of a specified range from the home device. We would also like to establish some method of indication to the home device that the receiver is beeping. At the end of this semester, we will demonstrate our project by separating the home device and the receiver by the necessary range to make the receiver start beeping.

Challenges

Technical Skills: The biggest challenge we will face is our overall lack of coding knowledge. We will need to learn the code to set up signal communication between the Arduino, bluetooth module, and the phone. Devising the project and list of goals will also pose some difficulties, because we currently lack the experience and background knowledge to grasp what the project will entail.

Size: Another concern is the ergonomic integrity of the device; we want the receiver to be wearable, durable, and safe for a child. Ultimately, the receiver is meant to be worn by a child in a situation in which the child might be active and running around. Realistically, our device should be small and sturdy so that it could not be easily broken by the user. Ideally, we would like our device to be small enough to wear as a bracelet or accessory; however, if the size cannot be reduced we may put the device in a wearable fanny pack-like accessory.

Distance: The HC-06 Bluetooth Module that we are looking to purchase only has a short range of ~10 meters (around 30 feet), which limits the scope of our project.

Cost: Another challenge to consider is the cost of the final product. Realistically, consumers would not be willing to pay a large sum for a product that they would only use for occasional situations or emergent situations. While some parents experience anxiety about losing their children in crowded places, many parents might not feel the need to purchase an emergency-oriented device that would only be useful during unplanned circumstances.
